Researchers used a specially engineered form of polarized light to enhance the perception of Boehm's brushes in about a dozen healthy volunteers. 

Electromagnetic (EM) wave absorbers with strong attenuation over a broad frequency range are critical for radiation protection and military stealth. However, magnetic alloys with high dissipation capacity remain challenging to achieve satisfactory impedance matching and enhanced high-frequency magnetic loss due to the scarcity of rational design for the distribution and size of magnetic particles. Herein, we design Prussian blue analogue (PBA) derived FeCo magnetoelectric composite nanocages by confinement engineering, achieving strong absorption capacity of -47.4 dB and broad bandwidth of 7.10 GHz at a small thickness of 1.9 mm. This work not only sheds light on the fabrication of FeCo magnetoelectric composite nanocages as efficient and wideband EM wave absorbers, but also propose a confinement engineering strategy for rational design of functional nanocomposites in multiple fields such as electromagnetics, electronics and optoelectronics.

Researchers have developed a programmable, multi-responsive soft actuator based on MXene materials that can reversibly deform under humidity, light, and magnetic fields. By introducing micro-ridge structures into a bilayer MXene/paraffin wax composite, the actuator enables controllable and complex shape transformations, offering new possibilities for soft robotics and intelligent devices.
